/**
 * Test for bug 19397. Description: If an imported plugin is specified as
 * optional in the plugin XML, the versioning information is ignored.
 * 
 * Scenario: pluginA requires pluginC (any version) and optionally 
 * pluginB_2.0.0, but pluginB's version is 1.0.0 (which by its turn
 * requires pluginD). Expected result: all plug- ins are enabled AND pluginA's
 * classloader does not import pluginB's classloader.
